摘　　要：通过理论分析和试验资料,得出群桩复合桩基的极限承载力不等于桩和地基土极限承载力之和的结论。提出了小桩距塑性支承桩复合桩基安全度的计算方法和特大桩距塑性支承桩复合桩基承载力计算的改进意见,可供设计此类基础设计时参考。On the basis of theoretical analysis and experimental results,it comes to the conclusion that the ultimate bearing capacity of composite pile foundation does not equal to the sum of ultimate bearing capacity of piles and soil between piles.It suggests the way to calculate the safety degree of composite plastically-bearing-pile foundation with small pile distance.Some improvement suggestions are made to the calculation of the bearing capacity of composite plastically-bearing-pile foundation with large pile distance and can be referential to similar foundations design.
